You don't want to try thumb cocking the cc version. The hammer is too stubby. The pistol is slightly shorter than the regular thunder in spite of the increased mag capacity due more to a new magazine design than to a longer magazine. The eight round mag is primarily why it is slightly taller than the 7+1 PPK/S and certainly much taller than the 6+1 PPK. It is thinner than a PPK/S through the grip area but not so much, if any, through the slide.
